Description

An artificial intelligence robot for vehicle service

technical field

The invention relates to the technical field of artificial intelligence robots, in particular to an artificial intelligence robot used for vehicle service.

Background technique

At present, the car ownership rate in cities is increasing rapidly, and parking spaces are becoming more and more scarce. It takes a lot of time to find or wait for an available parking space in hot roads, communities, and shopping malls during peak hours. It takes a lot of time to find and wait for a parking space. even more than driving from point of origin to destination. At present, the degree of automation of parking is very low, mainly requiring drivers to drive into vacant parking spaces by themselves. Some parking lots and vehicle service points can provide valet parking, key custody and other services, but many users do not want to hand over the driving rights of vehicles to service personnel due to reasons such as property safety, privacy, and avoiding joint liability for traffic accidents. Due to limited land resources, the shortage of parking spaces in big cities is difficult to alleviate in the short term. For smart cities, smart communities, and smart business districts, providing intelligent parking services has become an important point of improvement.

It has been decades since the birth of the robot system. With the improvement of technology, all kinds of robot equipment have been mainly used in the field of industrial production at first, and have gradually developed into the field of life services for ordinary people. In terms of parking services, the existing robot systems mainly include the automatic entry type of the three-dimensional garage and the autonomous vehicle transportation type.

For example, Chinese patent document CN206581661U discloses a kind of intelligent parking robot, the driver can park the vehicle in the parking area according to the random position, obtain the real-time image of the multi-angle vehicle body and the license plate information by the image acquisition and positioning system, confirm the vehicle position coordinates; A parking instruction is issued from behind the car, the manipulator moves to the top of the car, rotates and adjusts to be flush with the car body, lowers the manipulator to a suitable position on the car body, clamps the car tires, and then places the car to the parking position of the three-dimensional garage; this existing patent The robot equipment belongs to the automatic parking type of the three-dimensional garage, which can reduce the driving difficulty of the driver compared with the strict requirements of the traditional three-dimensional garage parking that must be straight in place. However, the installation and operation of the three-dimensional garage automatic entry robot system requires sufficient site space, and a large number of architectural renovations and facility constructions must be carried out on the existing parking lot, which is very expensive and many places do not have the construction conditions. In addition, the driver still needs to park the vehicle in the parking area adjacent to the three-dimensional garage with free storage spaces for the robotic arm to carry, which can save time and facilitate access for the driver.

On the contrary, autonomous vehicle delivery robot system can make the best use of the conditions of the existing parking lot to carry out the service. For example, Chinese patent document CN205713320U discloses an omnidirectional automatic access transfer robot and an automatic parking lot. It runs in all directions, including vertical, horizontal, oblique, in-situ turning, turning, etc. There are at least two sets of manipulators above the car body, which are used to hold the front and rear wheels of the car, and place the car on the fixed frame, or Pick up the car from the rack and send it to the parking space. For another example, the Chinese patent document CN106605033A discloses an automatic parking system, in which a pallet is placed on a fixed pillar in the handover space, and the car to be handed over is parked on the pallet by the driver, and then the vehicle is dispatched to drive under the pallet, The hydraulic lifting column on the dispatching vehicle is raised to lift the pallet from the fixed support, the dispatching vehicle carries the pallet and the vehicle on the pallet to a free place, and then lifts the pallet and the vehicle on the pallet The vehicle is unloaded at the placement place; when picking up the car, the pallet and the vehicles on the pallet are carried from the placement place to the handover space by the dispatching vehicle and placed on the handover space, and then the driver drives the car away. Autonomous vehicle delivery robots generally have the function of autonomous navigation and driving. Using autonomous vehicles to transport robots, it is only necessary to build a vehicle handover area near the entrance and exit of the existing parking lot, and then deploy a certain number of the above-mentioned robots. There is no need to add a large number of facilities, and the upgrade scale and cost are controllable. The driver only needs to drive the vehicle to the handover area and park the vehicle on the pallet or fixed frame in the handover area. The robot will automatically move the vehicle to the free parking space in the parking lot and park it. The driver does not need to spend any more time searching or waiting in line. The time of free parking spaces; when picking up the car, the driver goes to the handover area and waits for the robot to bring his vehicle, which also avoids the trouble of often forgetting where the vehicle is parked in large parking lots; the driver does not drive into the parking lot, there are It is beneficial to the internal order and standardized management of the parking lot.

However, the existing autonomous vehicle delivery robots and their application systems still have the following deficiencies:

First of all, access to the car needs to be carried out in a fixed handover area, because when storing the car, it is necessary to place the vehicle itself or the pallet carrying the vehicle on the robot carrier with the help of auxiliary frames such as fixed pillars and fixed frames in the handover area. When driving, it is also necessary to move the vehicle itself or the pallet carrying the vehicle from the robot carrier to the auxiliary frame such as fixed pillars and fixed frames, and then drive away by the driver; and the auxiliary vehicles such as fixed pillars and fixed frames that can be installed in the handover area The number of racks is also limited, so in the handover area of the parking lot with a large traffic flow, it is inevitable that there will be vehicles waiting in line or car pickers queuing up. The current car pick-up link is that the user sends a pick-up command to the application system. The system allocates the time period for the user to pick up the car and which auxiliary frame the car is sent to the handover area. The user needs to pick up the car strictly according to the scheduled time and location. If the car owner fails to arrive at the agreed time when picking up the car, it will affect subsequent users to pick up the car. We hope to achieve a model that does not rely on a limited number of auxiliary frames, especially the working mode of storing and picking up cars anywhere, that is, when the car comes to any position in the handover area, a robot will come to carry the vehicle, and the car will be picked up. Sometimes users only need to stand on the sidewalk in the handover area, and a robot will send their vehicles. In addition, the informatization and intelligence of the robot itself needs to be further improved. For example, users hope to be able to know the status of the vehicle in real time during the storage period, especially when the robot is handling the vehicle, and hope to provide a more concise and effective service than swiping the parking card for the user when accessing the vehicle. authentication method.

Therefore, it is hoped to propose an artificial intelligence robot for vehicle service to solve the above-mentioned problems.

After the driver drives the vehicle to the parking lot where the robot is deployed, he can deliver the vehicle to the artificial intelligence robot in the handover area, and then do his own thing, and the robot will carry the vehicle to the free parking space in the parking lot for parking.

The present invention not only solves the current problem that users need to manually search for parking spaces and wait in line to park vehicles, but also uses artificial intelligence identification and analysis technology to realize intelligent judgment and switching between various driving and operation modes of the robot, and realizes parking in the parking lot. The working mode of storing and picking up cars anywhere in the handover area, that is, when the car comes to any position in the handover area, a robot will come to carry the vehicle, and when picking up the car, the user only needs to stand on the sidewalk in the handover area, and the robot will pick it up.
